NUT-SPLITTER.

Specification of Letters Patent.

Patented Aug. 53,1913.

Application filed January 14, 1913. Serial No. 742,017.

To all whom it may concern do it known that I, EDGAR J. CHANDLER, acitizen of the United States, residing at Everett, in the county ofSnohomish and State of lVashington, have invented new and usefulImprovements in Nut-Splitters, of which the following is aspecification.

The invention has for its object the provision of a tool particularlydesigned for removing nuts or burs from bolts, rods or like fasteningswhen it becomes practically impossible to remove the same in theordinary way.

When a nut has become fixed upon a bolt or rod by corrosive action itbecomes necessary to split the same in order to remove it and this isusually attended with vexation and requires the services of twooperators, the one to hold a support beneath the nut while the otherholds the chisel and delivers a blow thereon.

The present invention provides a tool which will enable the work ofcutting a nut from a bolt, rod or other fastening by a single operatorwith comparative ease and despatch, since the tool embodies a supportand chisel and may be held in one hand of the operator while a hammergrasped in the other hand may be used to deliver a blow upon the chiselto split the nut.

A further purpose of the invention is the provision of a tool which maybe easily adapted to nuts of different sizes so that the work ofremoving a nut from a bolt may be effected in a rapid manner and withcomparative ease without requiring the services of an assistant eitherto deliver a blow upon the chisel or to hold the hammer or like deviceagainst the nut to receive the force of the blow when the chisel isstruck.

Figure l is a view in elevation of a tool for removing a nut from abolt, rod or other fastening, showing the same in operative position.Fig. 2 is a front view of the tool, the hammer head being in verticalsection. Fig. 3 is a top view of the tool, the outer portion of thehandle being broken away. Fig. 4 is a horizontal section on the line50-00 of Fig. 1. Fig. 5 is a detail perspective view of the connectionby means of which the handle is adjustably secured to the hammer head.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawing, by the samereference characters.

The tool embodies a hammer head 1 and a chisel 9., the hammer head beingattached to a handle 3 in any manner. The hammer head may be of anyconstruction and the handle 3 may be attached thereto in any way. Thechisel 2 has a stem 4 which constitutes a guide to direct the chisel inits movements and to hold it in proper place upon the hammer head. Thestem 4: preferably constitutes a part of the chisel, the latter beinglocated in advance of the stem. The hammer head is formed with anopening 5 to receive the stem 4, said opening be ing contracted near itsupper end to form an inner shoulder (3, which receives the end thrust ofan expansible helical spring 7 mounted upon the stem 4t and confinedthereon by means of a nut S threaded upon the inner or lower end of thestein. The nut 8 is relatively long to admit of adjustment so as to varythe tension of the spring 7. In the preferable construction two stems 4are provided, the one being a duplicate of the other and each beingarranged to operate in an opening 5 formed in the hammer head 1 and eachhaving a spring 7 and nut 8. The stems l are connected at their upperends to each other and to the chisel 2. The provision of a pair of stems4 insures holding the chisel in a given position with reference to thehammer head. The chisel occupies a position midway between the stems 4:so that the projecting end of the bolt or rod 9 may pass through thespace formed between the upper ends of the guide stems when the tool isfitted to the nut 10 to be cut from the part 9.

When it becomes necessary to remove the nut from a bolt, rod or likepart 9 by splitting the same the tool is arranged substantially asindicated in Fig. 1, that is with the hammer head 1 beneath the nut 10and the chisel above said nut with its edge in line with the center ofthe bolt opening. The spring 7 exerts a downward pull upon the stem andchisel and holds the latter in engagement with the nut. The handle 3 isgrasped by one hand of the operator and the other hand is supplied witha hammer or other tool for delivering one or more blows upon the chisel2 to split the nut, which when cleft may be easily removed.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

In order to provide a tool that may be conveniently used in allpositions it has been found necessary to attach the handle 3 to thehammer head in such a manner as to admit of varying the relativeposition of the handle, thereby enabling the tool to be used in closequarters and in places difiicult of access. For this purpose aconnection 11 is fitted in an opening 12 formed transversely in thehammer head, said opening being enlarged at one end, as indicated at 13,to form a flaring wall for an enlarged portion 14 of the connection 11to engage by a wedging action. The connection 11 is in the nature of astem or rod which is externally threaded to fit Within the opening 12which is correspondingly threaded. The end of the connection to whichthe handle 3 is attached is split or forked, the fork members havingtheir inner sides corrugated or roughened to match correspondinglycorrugated or roughened sides at the attaching end of the handle 3. Abolt 15 passes through registering openings formed in the forked end ofthe connection 11 and in the attaching end of the handle 3. The handlepivots on the bolt or fastening 15 and the latter may be used to drawthe fork members of the connection together so as to cause thecorrugated faces or sides to engage and thereby hold the handle in theadjusted position. The fork members may be further drawn together andheld in fixed position by the flaring portion 14: at' the base of thefork members engaging and riding upon the flaring wall 13 of theenlarged end portion of the transverse opening 12. The connection 11 maybe turned by fitting a wrench or other suitable tool thereto. By backingthe connection 11 and loosening the bolt or fastening 15 the forkmembers spread by a spring action, thereby disengaging their corrugatedfaces from the corrugated faces of the attaching end of the handle sothat the latter may be turned to any relative angular position, afterwhich the same is made secure by tightening the fastening 15 andscrewing the connection 11 into the threaded opening 12.

Having thus described the invention what is claimed as new, is

1. The herein described tool comprising a hammer head provided with ahandle and having parallel openings, a chisel having spaced stemsarranged to operate in the openings of the hammer head, springs mountedupon said stems within the openings of the hammer head, and nutsthreaded to the stems for confining the springs thereon.

2. In a tool of the character described, the combination of a hammerhead provided with a chisel and having a transverse opening which isflared. at one end, a connection fitted in the transverse opening andhaving one end forked and provided at the base of the fork with a flaredportion to engage the flared end of the transverse opening of the hammerhead, a handle secured between the fork members of the connection, andmeans for drawing said connection into the opening of the hammer headwhereby the tapered portion rides upon the flared portion of the openingand thereby causes the fork members of the connection to grip theattaching end of the handle.

In testimony whereof I aifix my signature in presence of two witnesses.

EDGAR J. CHANDLER.
